Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483210, here are decompositions:

41 + 31483169 = 31483210
47 + 31483163 = 31483210
113 + 31483097 = 31483210
149 + 31483061 = 31483210
233 + 31482977 = 31483210
263 + 31482947 = 31483210
389 + 31482821 = 31483210
431 + 31482779 = 31483210

Showing the first eight; more decompositions exist.
